this weekend is pretty busy, but tonight i did get the chance to sit down and actually think about how differing update rates were causing this jitter. i fixed the problem (related to interpolation), and then reintroduced it. but i definitely understand the cause of the problem and can now start to look solutions.
...right after mother's day is over tomorrow.
there's going to be several more days of gifs of me just walking around showing off the current state of the camera. haha.
